Hi,

As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

What kind of noise? Where is the noise coming from? Inside the unit or where the compressor is?

This will help You. I had to replace compressor. It died due to the 100% clogged coils. REPLACING COMPRESSOR TRUE AIR BEER COOLER R134A

This compressor burned out due to lack of maintenance, condenser coils were clogged 90%. compressor overheated and blow out. I made video how To change compressor and filter dryer. Its a beer cooler. REPLACING COMPRESSOR TRUE AIR BEER COOLER R134A

Either your coil is blocked with paper or wrap, or you have a refrigerant leak in the coil and the little bit of gas that's left is flashing as it enters the coil. Make sure that the cooling coil and condenser is clear and the fans are running. That's all you can do without refrigeration tools. Good luck and hope this helps

Cold Tech gaskets can be obtained from Case Parts Co. 800-421-0217 or RHS Parts 800-537-8300, per jimex corps final technical spec. sheet. I hope this helps.

Keep the prep top table pans covered when not in use. Never leave empty holes where pans should be. If the pans are empty put a couple of inches of water in them to keep some heat load there. Check the door gaskets and door seal on the base doors. Make sure the thermostat is set on number 5. If all of this checks out probably need a new thermostat, but if it's erratic I suspect you will find it's one of the former problems.

Have the unit leak test after pressurizing with "Nitrogen"

Hi

Sounds like you are correct, unless the door seals are not in good order, air leaking in can fool the thermostat.

If it has a top section that the pans for pizza ingredients sit in check that the airways are clear and that the tins and lids fit properly.

Sounds like it is on its way out. You can get a new thermostat HERE If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

Question edited for clarity. The Service Manual says that the wiring diagram is hidden in various parts of the unit. https://www.manualslib.com/manual/1177583/True-Gdm-Series.html?page=43&term=wiring+diagram&selected=1#manual It doesn't appear to be all in one place, but you could contact their Customer Service, or Technical Service Department? https://www.google.com/search?q=true+gdm-35em+wiring+diagram ..

If the left-hand door of your True TBB-3G fridge is sagging and creating an air gap at the bottom of the frame where it meets the cooler, here are some steps you can take to fix the issue:

1. Check the door hinges: Inspect the hinges on the door and the frame of the fridge. Look for any damage or wear that may be causing the door to sag. If the hinges are damaged, they may need to be replaced.
2. Adjust the door hinges: If the hinges are in good condition, try adjusting them to see if this resolves the issue. Use a wrench to loosen the screws that hold the hinges in place, and then adjust the hinges up or down as needed to align the door with the frame. Tighten the screws back in place when you are finished.
3. Check the door gasket: If the door gasket is worn or damaged, it may not be sealing properly and causing air gaps. Check the gasket for any damage or signs of wear, and replace it if necessary.
4. Check the door closer: The door closer on the left-hand side may be damaged or worn, causing the door to sag. Inspect the closer and look for any signs of damage. If it is damaged, it may need to be replaced.

If none of these steps resolves the issue, you may need to contact a professional repair service to help diagnose and fix the problem.

It's possible that the issue may be with the thermostat or the compressor. If the thermostat is not working properly, it may not be regulating the temperature correctly. Similarly, if the compressor is not working properly, it may not be able to cool the fridge down to the desired temperature. It's best to have a professional take a look and diagnose the issue. Another possible cause is the refrigerant levels, if the refrigerant is low this can cause the compressor not being able to cool the fridge properly and will need to be refilled by a professional.

This is a $3,600 commercial undercounter fridge. Great make and I have used many of them in my 50 year catering career. There is nothing on fixing Error 13. Pages 76 and 79 state 'Communication Error'.

The freezer door being open all night cause the compressor to run all night continuously trying to cool the unit down. This caused an increase in resistance and tripped the breaker. It may stabilise, but it may need a service call to fix the issue. It may also be a lazy breaker and it is the breaker that needs swapping out. you can normally compare them against adjacent breaker, a lazy one feels soft and doesn't snap of Off when you move is slowly to the Off position. They also feel different when switching to On. I have spent a 50 year career in catering and hospitality fighting fridges and freezers, electrics and plumbing. Now retired :>) Get this fixed by Easter because in my experience, it will break down on Saturday at 8:00pm!

You mean 'low as it can go', talking temperature not numbers. The temperature is too high. You need a refrigeration engineer. You either need a top up of gas or the thermostat has failed. They are great fridges, I have had lots of them in my career.

without knowing age of unit, I suggest replacing the motor. Sounds like the armature is worn the bearings and is moving inside the windings of the motor. I would do that first before moving forward with any other repairs.

Please forward model and serial so I can be sure I am addressing the correct unit. Thanks.
